What is GDPR?
The General Data Protection Regulation (GDPR) is a data privacy and security law enacted by the European Union (EU) that came into effect on May 25, 2018. It aims to protect the personal data of EU citizens and residents, giving individuals more control over how their personal data is collected, processed, stored, and used. GDPR applies to all organizations, regardless of location, that handle personal data of individuals within the EU, making it a critical regulation for businesses worldwide.
GDPR introduces several key concepts, including data subject rights, lawful processing of personal data, data protection principles, and strict requirements for data security. Non-compliance can result in severe penalties, including fines of up to €20 million or 4% of the global annual turnover, whichever is higher.
Privacy and Security Controls Required for GDPR Compliance
For small and medium-sized businesses (SMBs) to comply with GDPR, a variety of privacy and security controls must be implemented. These controls ensure the proper handling of personal data and the safeguarding of this information against unauthorized access, loss, or breach.
Data Mapping and Inventory involves identifying and documenting all personal data collected, processed, and stored by the business. This includes understanding the data flow, storage locations, and any third-party processors involved. To implement this, a data inventory should be created that details the types of personal data, the purposes for which it is used, data retention periods, and data sharing practices.
Lawful Basis for Data Processing requires establishing a legal basis for collecting and processing personal data, such as consent, contract performance, legal obligations, vital interests, public tasks, or legitimate interests. Ensure that for each data processing activity, there is a documented lawful basis. Obtain explicit consent from individuals where necessary and provide clear information about data processing activities.
Data Subject Rights ensure mechanisms are in place to uphold the rights of individuals, including the right to access, rectify, erase, restrict processing, data portability, and object to processing. Implement processes to handle data subject requests promptly and establish a policy for handling these rights within the required timeframes.
Privacy Notices and Transparency require providing clear and transparent information to data subjects about how their personal data is processed. Update privacy notices and policies to include detailed information about data processing activities, including the purposes of processing, data retention periods, and data subject rights.
Data Protection by Design and Default means incorporating data protection principles into the design of business processes and systems that handle personal data. Integrate privacy features into products, services, and systems. Use data minimization, pseudonymization, and encryption to protect personal data.
Data Breach Response and Notification necessitate establishing procedures for detecting, reporting, and investigating personal data breaches. Develop a data breach response plan that includes processes for identifying breaches, assessing the impact, notifying affected individuals, and reporting to the appropriate Data Protection Authority (DPA) within 72 hours.
Data Protection Impact Assessments (DPIAs) involve conducting DPIAs for processing activities that are likely to result in high risks to the rights and freedoms of individuals. Identify processing activities that require DPIAs, assess the potential risks, and document the measures taken to mitigate these risks.
Data Processor and Third-Party Management ensures that third-party processors handling personal data on behalf of the business comply with GDPR. Establish Data Processing Agreements (DPAs) with third-party vendors, outlining their obligations to protect personal data and ensure they implement adequate security measures.
Security of Processing requires implementing appropriate technical and organizational measures to ensure the security of personal data. Implement controls such as data encryption, access controls, secure data storage, regular security testing, and employee training on data protection.
Data Retention and Deletion define data retention periods and implement processes to securely delete personal data when it is no longer needed. Establish a data retention policy and employ secure data deletion methods, such as data wiping or degaussing, to ensure the complete removal of personal data.
Using the NIST 800-53 Framework for Implementing GDPR Controls
The NIST 800-53 framework consists of a set of security and privacy controls across various control families that align with GDPR's requirements.
